Abstract
A TUNER (9) OF FOR A DIGITAL SATELLITE TELEVISION RECEIVER COMPRISES A SINGLE CONVERSION STAGE WHICH PRODUCES AN IF SIGNAL AT A LOW ENOUGH FREQUENCY TO PERMIT A SAW FILTER (913) TO BE USED TO PERFORM SYMBOL SHAPING AS WELL AS THE NORMAL IF FILTERING FUNCTION. THE LOCAL OSCILLATOR (911) IS CONTROLLED BY A PHASE LOCKED LOOP (911, 917) TUNING CONTROL IC NORMALLY USED TO CONTROL THE LOCAL OSCILLATOR OF A TUNER OF A CONVENTIONAL BROADCAST OR CABLE TELEVISION RECEIVER. IN AN EXEMPLARY EMBODIMENT FOR TUNING RF SIGNALS PROVIDED BY A BLOCK CONVERTER (3) IN THE 950 TO 1450 MHZ FREQUENCY RANGE, THE IF HAS A CENTER FREQUENCY OF 140 MHZ FIG 1
